COMBINATION INSTRUMENT FOR-CLEANING GAS-COCKS.

SPECIFICATION forming part of Letters Patent No. 259,717, dated June 20, 1882.

Application led March 20, 1882.

To all whom it m ay concern Be it known that I, MATTHEW PRIOR, a citizen ofthe United States, residing atRevere, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in a Combination Instrument for Cleaning Gas Cocks or Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The subject of this invention is a combination instrument adapted especially to the purpose of keeping gas-burners in effective condition, though applicable to various purposes; and it consists in a hollow handle of suitable construction to contain a portion of the instrument and having a pipe-wrench pivotedto it,

cover the opening in the handle, and conceal and prevent loss or misplacement of the articles therein.

The drawings accompanying this speciieation represent, in Figure l, an isometric elevation of an'instrument containing my invention with the pipe-wrench opened to permit of access to the interior of the handle, while Fig. 2. is a like view with the Wrench closed and in working condition. Fig. 3 is a view of the implement contained within the hollow handle. Fig. 4 is a vertical section ot' the handle and wrench.

In the above-nameddrawings, A represents a handle substantially in the form of the han- 'dle of an ordinary pocket-knife, the sides of such handle being shown at a a, and the back, which is secured solidly to the sides instead ot' being in the form of springs, as in pocketknives, at b.

B represents the pipe-wrench as composed of a straight shank or body, c, and a terminal U-shaped head', d, composed of two jaws, e f, t-he jaw e being constructed at an angle with the shank c, while the extremity or jaw f departs from the jaw e at an aouteangle, the in ner face of the ja-w c being smooth and that of the jaw f serrated or toothedto grasp a cylin- (No model.)

drical object-such as a gas-pipe-after the manner of pipe-wrenches in general. The free y end of the shank c is converted into a screwdriver, c', for convenience in loosening and de- 5 5 taching as well as applying the cocks of gasi burners or as a screw-driver for universal use, and the main portion of' the said shank c is contained within and fills the outer portion or mouth of the opening or chambergof the han- 6o die. The shank ot' the wrench constitutes a cover to the chamber of the handle, and is pivoted within one end of such handle by a pivot,

h, in order to open or close such chamber. When closed, as shown in Fig. 2, the implement is an eli'ective pipe-Wrench and screwdriver, While the pivoting of the shank ofthe wrench to the handle enables the chamber of the latter to be opened, as in Fig. 1 of the drawings. 7o

To hold the shank of the wrench closed, a plate-spring, l, is secured at one end to such shank, and exerts its stress upon a pin,j, spanning the two sides of the handle parallel with the pivot 7L and outside ofthe shank. 75

The remaining portion of my instrument consists offour implements, which for convenience are connected together by a pivot. These consist, first, of a iiat, thin blade, k, adapted to clear the slit or oritice of a gas- 8o burner; second, of around, straight, line wire,

l, for clearing the small circular holes formed in some classes of gas-burners; third, in aseoond stouter wire,m, curved at one end, adapted to-clean theinside of the parts of a gas-burner; 8 5 and, fourthly, in a swab composed of a straight shank, n, and a loop, 0,' upon its outer end, to contain a bit ot' cloth, tow, or other material, after the manner of gun swab sticks, and adapted to clean the interior of a gas burner 9o or pipe. As before stated, these four implements are preferably connected togeth er, and

to accomplish this and permit them to be readily used I form each with ailat head, p, and I pivot these heads together by a common pivot, q, as shownin Fig. 3 of the drawings. When folded compactly the fourimplements may be stowed within the chamber of the handle of the instrument, and thus deposited occupy no valuable space, and are out of sight as Wellas roo protected from misplaeement or loss.

The instrument above described is simple,

compact, and may be made at small cost. It is valuable for keeping gas-burners in repair and for various uses in the mecha-nic arts.

I clainil. The combined pipe-wrench and screwdriver consisting of the shank c, terminating at one end in the screw-driver c', and at the other inthe U-shaped head, with its smooth and serrated jaws ef, in combination with the ehambered handle A, the wrench being pivoted to the handle and constituting a cover to its chamber, substantially as explained.

2. The pipe-wrench composed of the shank c, with its U-shaped head d, in combination with the chambered handle A, when the said shank is pivoted to and constitutes a cover to the chamber of the handle, as explained.

3. The combined pipe-wrench and screwdriver consisting of the shank c, terminating MATTHEW PRIOR.
